Title: Fm receiver
Inventor: MIKAMI TAKU
IPC: H04B1/26
Filed: 1986-12-02
Abstract: PURPOSE:To reduce a circuit scale and to decrease a power consumption by using the output of the local oscillator of a receiver as the clock of a pulse counting type FM demodulator when an PM signal is demodulated by the pulse counting type FM demodulating circuit, in the FM receiver to remove a base band signal. CONSTITUTION:The output of a local oscillator 13 is added through an AND gate 11 to a counter 8 and the counting value is compared with the set value set beforehand by a digital comparator 121. When two values are coincident, a coincidence pulse outputted from a digital comparator 121 is added to the R terminal of a resetting-setting flip-flop RS-FF6. For that reason, the signal of an H level outputted from a Q terminal is changed to the signal of an L level and a pulse train, in which a width is tau, passes through a low pass filter and a base band signal is fetched. Namely, since a clock oscillator is eliminated a circuit scale is made smaller and the power consumption is decreased.
